以上是log
下面是调用报错的代码：

package com.apc.service;

import org.nutz.ioc.loader.annotation.Inject;
import org.nutz.ioc.loader.annotation.IocBean;
import org.nutz.mvc.annotation.At;
import org.nutz.mvc.annotation.Fail;
import org.nutz.mvc.annotation.Ok;

import net.sf.ehcache.Cache;
import net.sf.ehcache.CacheManager;
import net.sf.ehcache.Element;

@IocBean
@At("/faction")
@Fail("http:500")
public class FactionService {

//	@Inject
//    protected Dao dao;
//	
//	
//	@At("/test")
//	@Ok("json")
//	public int testTableCount(){
//		int count = 0;
//		count = dao.count(Faction.class);
//		return count;
//	}
	@Inject
	private CacheManager cacheManager;
	
	@At("/test2")
	@Ok("raw:json")
	public String testToken(){
		Cache cache = cacheManager.getCache("configCache");
		Element value = cache.get("fangjingping");
		if(null == value){
			cache.put(new Element("fangjingping", "haha,this is value"));
			return "this is no value";
		}else{
			return value.toString();
		}
	}
}

下面是js文件以及ehcache.xml

var ioc = {
    // 直接初始化Ehcache,默认找ehcache.xml文件哦
    cacheManager : {
        type : "net.sf.ehcache.CacheManager",
        factory : "net.sf.ehcache.CacheManager#create"
    }
    /* // 与shiro共享一个ehcache示例的方式
    cacheManager : {
        type : "net.sf.ehcache.CacheManager",
        factory : "net.sf.ehcache.CacheManager#getCacheManager",
        args : ["nutzbook"] // 对应shiro.ini中指定的ehcache.xml中定义的name
    }
     */
};


<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="ehcache.xsd">

        maxElementsInMemory="20"
        eternal="false"
        overflowToDisk="false"

        timeToLiveSeconds="7190"
 </defaultCache>  
 
<cache>
        name="configCache"
        maxElementsInMemory="100"
        maxElementsOnDisk="1000" 
        eternal="true"
        overflowToDisk="false"
        timeToIdleSeconds="5" 
        timeToLiveSeconds="6"
</cache>

</ehcache>

用的是ehcache 2.10.2

xml写错了个， 右括折号的位置不对

<cache
        name="configCache"
        maxElementsInMemory="100"
        maxElementsOnDisk="1000" 
        eternal="true"
        overflowToDisk="false"
        timeToIdleSeconds="5" 
        timeToLiveSeconds="6">
</cache>

defaultCache也是这个问题

建议拷贝默认ehcache.xml来改，得符合xml的格式要求
